Non-roster invitee S Sam Proctor (Oklahoma) joins 2012 draft picks WR Ryan Broyles, and LBs Ronnell and Travis Lewis to give Detroit’s rookie orientation a strong Sooner presence. The camaraderie between the Oklahoma players on the field is evident during workouts, and LB Ronnell Lewis admitted the presence of former college teammates has made the transition to life in the NFL easier. “The fact that we played with each other and know how to push each other to compete is good,” he said. “It’s going to keep us going.”
